Abstract

In this paper a novel online chromatic dispersion monitoring method employing the spectral shift in the semiconductor optical amplifier (SOA) is proposed and experimentally investigated. The power of the long wavelength side of the output signal through the SOA is extracted by a narrow bandwidth filter, and is utilized to measure the dispersion of the signal. The experiment shows that the ratio of the filtered power to the total power decreases 10 dB while the absolute value of the dispersion increases 700 ps/nm, with the input average power kept constant.
